RIP

Former NFL lineman Bryan Robinson -- who spent 14 years in the league -- was found dead Saturday in a motel room in Milwaukee.

Details surrounding his death are slim. Unclear why Robinson was at the motel. The Milwaukee Medical Examiner's office is investigating, according to the Chicago Tribune.

The 41-year-old -- who played for the Bears, Cardinals, Rams, Bengals and Dolphins -- was a solid NFL player. He played in Super Bowl XLIII with the Cardinals in 2009.

Motorhead's Lemmy Kilmister's memory will live forever at his rock 'n' roll home -- The Rainbow Bar & Grill.

The famed restaurant/bar is a coveted part of the Sunset Strip ... the place John Belushi had his last meal the night he died, the joint where John Lennon threw back drinks, and the favorite haunt of Led Zeppelin, Elton John and countless other rock stars and celebrities.

The patio area at The Rainbow Bar & Grill is being renovated and re-named "Lemmy's Lounge" ... it's the place Lemmy always hung before his death last December. In an awesome move, they're using Lemmy's favorite bar stool as a focal point of the redesign.

And there's a $20k bronze life-size Lemmy statue.

Former 'Voice' competitor Christina Grimmie is dead after a shooting in Orlando.

Christina was doing a meet and greet with fans Friday night following a concert ... when a man walked up to her and simply opened fire. Her brother tackled the shooter, but the man was able to get free enough to shoot and kill himself.

This picture was taken minutes before Christina was shot.

Christina was rushed to a hospital, but died early Saturday morning from her injuries. Police are hailing her brother as a hero for stopping the massacre of countless more people.

Christina had opened Friday night for the band, Before You Exit. Since finishing in third place on "The Voice" Season 6 (2014) ... Christina signed with Island Records, and was reportedly working on an album.

Grimmie was 22.

We've learned Christina's twitter account was hacked, but her team has regained access and taken down the message.

Muhammad Ali's memorial service was punctuated by emotional and humorous stories about his life ... as told by his family and famous friends.

Billy Crystal was a close friend and told the packed arena in Louisville about the first time they met ... and how Ali reacted to Crystal's impression of him.

Many, many others spoke during the nearly 4-hour long ceremony. A scruffy Crystal joked, "I was clean shaven when this started."

Ali's widow, Lonnie ... 3 of his daughters ... Sen. Orrin Hatch and Bryant Gumbel also shared their memories.

President Bill Clinton delivered the final eulogy of the memorial, talking about the one thing Ali never got enough credit for -- his intelligence.

A famed director is suing the W, claiming the hotel blocked him from rescuing his husband from suicide.

Norman Buckley, who directed "Gossip Girl" and "Pretty Little Liars," claims in a new lawsuit his husband, Davyd Whaley, had disappeared from their West Hollywood home in 2014 and checked into the W in Hollywood under an alias.

Buckley says Davyd was suffering from PTSD and paranoia and the hotel could tell at check-in something was terribly wrong. Buckley says Davyd appeared, "nervous, scared and fidgety."

According to the lawsuit, Buckley saw a credit card charge from the W and called the hotel, saying he was Davyd's husband and this was an emergency situation and Davyd needed his meds, STAT.

Buckley claims the hotel was unwilling to help ... in fact they wouldn't acknowledge Davyd was a guest.

Buckley eventually got the Sheriff's Dept. to call the hotel, but by then it was too late. Davyd had killed himself in his room, several hours before.

The suit alleges had the W people treated it as a true emergency, Davyd would still be alive.

We reached out to the W. So far, no word back.

Mike Tyson and Will Smith were among the early arrivals for Muhammad Ali's memorial service -- and served as pallbearers as the procession through Louisville started.

The 19 mile journey through Ali's hometown began Friday morning after Tyson, Smith, Lennox Lewis and several of Ali's family members carried his coffin to the waiting hearse.

The procession will end up at Yum! Center arena where Bill Clinton will deliver the eulogy for Ali at the memorial service.

Kareem Abdul-Jabbar, who called Ali his mentor, is also in Louisville.

The memorial service is scheduled to begin at 10 AM PT ... and TMZ will be live streaming.

7:55 AM PT -- A rep for the the Lucas County Coroner's office tells us Howe died of "natural causes." They will not be investigating his death.

Hockey legend Gordie Howe died Friday morning in Ohio.

According to reports, Howe was at his son's home in Toledo when he passed away. He had suffered a stroke last year, but his family said he recovered well after that.

Howe was 88.

The Detroit Red Wings superstar held most of the NHL records that Wayne Gretzky eventually broke.

Howe was a 23-time All-Star in the league, and played an astounding 26 seasons in the NHL (still a record) ... plus another 6 in the World Hockey League. His 1,767 NHL games played is also a record.

Gordie retired at the age of 52 ... following one season with the Hartford Whalers in 1980.

Interesting pic we dug up -- in 1990, Howe was honored at the All-Star Professional Sports Awards alongside Muhammad Ali, Jim Brown and Rod Laver.

Muhammad Ali's family and close friends from the boxing world attended the first of 2 memorial services planned for him in Louisville.

Laila Ali cradled her young daughter during the Jenazah -- an Islamic prayer service. Sugar Ray Leonard and Rev. Jesse Jackson were among the celebs who showed up -- and about 16,000 tickets were handed out to fans.

Muhammad Ali will be laid to rest in truly hallowed ground because the cemetery is chock-full of celebs.

After his memorial services -- Thursday and Friday -- Ali will be buried in Louisville's Cave Hill Cemetery which is already the final resting place to:

- THE Colonel Harland Sanders of KFC fame
- Meriwether Lewis Clark Jr. ... who created the Kentucky Derby
- Patty Hill ... who wrote the "Happy Birthday" song
- Pete "The Gladiator" Browning ... the baseball player who popularized Louisville Slugger bats
- J. Graham Brown ... inventor of the Hot Brown Sandwich (look it up, it's delicious)

Sugar Ray Leonard is heading to Louisville to attend Muhammad Ali's funeral -- telling TMZ Sports the man had a tremendous impact on his life and he wants to pay his respects in person.

Leonard says he's not scheduled to speak at the event -- but would if he was asked. However, he admits it's a pretty tough task to eulogize a man who accomplished so much.

He also has a message to the fans caught up in the melee over funeral tickets this morning -- CALM DOWN!!!!

The doctors who cleared Kimbo Slice to fight at Bellator 149 in February found NO SIGNS of serious heart problems during pre-fight health exams ... this according to Bellator.

A Bellator spokesperson tells us ... Slice was not only required to pass a physical exam before his fight (as with all fighters over the age 35), he also had to pass an EKG and an EEG in order to be cleared.

Slice passed away this week -- and doctors said his heart was in such bad shape in his final days that he needed a transplant.

But Bellator says Slice would have been pulled IMMEDIATELY if there were any red flags back in February.

“If there was ANY sign that Kimbo was not healthy enough to fight, we would NOT have allowed him to fight."

Ex-NBA player and 76ers assistant coach Sean Rooks died of heart disease... this according to the Philadelphia Medical Examiner's Office.

Sources told TMZ Sports ... the 46-year-old suffered a heart attack during dinner on Tuesday night.

Now, a rep for the M.E.'s office says the coroner has examined Rooks' body and "believes Rooks died of heart disease."

We're told additional testing will take place to confirm that finding.

An honest moment from legendary boxing trainer Freddie Roach -- who says he's sad about Muhammad Ali's death because it makes him think about "what I maybe have to look forward to."

Just like Ali, Roach has Parkinson's disease -- and while outside of Ecco in NYC, Roach told us the two actually bonded about their conditions when Ali came into his gym about 15 years ago.

"As soon as he started hitting the heavy bag, his tremors went away," Roach said ... "I said we have something in common, because when I do mitts, my tremors go away."

"I think it's more of our comfort zone. We're boxers, we're both very comfortable doing that."

He continued, "I'm a little bit sad that he passed away ... I wonder what I maybe have to look forward to sometimes."

Muhammad Ali's memorial service is still 2 days away, but thousands of fans are ready and willing to fight for a ticket to get inside.

Ali's memorial is scheduled to go down Friday morning at Louisville's KFC Yum! Center -- but the crowds started lining up Tuesday night and waited until sunrise to make sure they got a seat. 15,000 tix were gone in about an hour!

Even though they were super early birds, some of the fans got out of hand just before sunrise -- pushing and shoving. Security was able to shut it down before anyone was hurt -- and police are now helping with crowd control too. No one was arrested.

Ex-NBA player and current Philadelphia 76ers assistant coach Sean Rooks has died ... the team announced in a statement.

The 46-year-old -- who starred at the University of Arizona -- played 12 seasons in the NBA ... including stints with the Lakers, Mavericks and Timberwolves.

Our sources tell us ... it appears Rooks may have had a heart attack during dinner.

Rooks' mother issued a statement saying, "It is with deep sadness and overwhelming grief that we mourn the sudden loss of my son, Sean."

"Our family asks that our privacy be respected as we grieve during this incredibly difficult time."

Cops say they can't find a shred of evidence that proves OKC Thunder co-owner was trying to kill himself when he slammed his SUV into a concrete bridge back in March ... despite a 2 month investigation.

Aubrey McClendon had been charged with conspiracy hours before the crash for his alleged role in an illegal energy scheme ... and many people thought he took his own life out of shame.

But the Oklahoma City Police Dept. says a team of detectives and accident experts looked into the crash ... and spoke with a bunch of McClendon's friends and say there's nothing that points to suicide.

Now, cops also say they can't be 100% certain ... but at this point, they're convinced he didn't crash on purpose.

The coroner determined McClendon died from blunt force trauma -- but his body was so badly burned in the fire that ensued, they needed to bring in a dentist to identify his body.
